ATI's secret weapon is called Sideport and this is a single memory chip that can boost the graphic performance.
According to AMD, Sideport will boost performance by 10 to 15 percent and this DDR3 memory will run at 400MHz, 533MHz or top 667MHz. Naturally, the 667MHz will run the board the fastest and in Crysis it promises close to a 15 percent increase, compared to 790GX performance without Sideport memory.
